our new multicolumn layout [please test!]

Hi! I have added initial support for multicolumn layouts to layout.inc site_footer() and site_header(), and modified source.php to use this layout for its two column display. I have tested the page in Mozilla 1.4 and Konqueror 3.1-12, and it looks very similar to the previous twocolumn layout. I have selected source.php because it is far not mission critical and I can show you how it works online and ask you to test it out in other browsers (primarily multiple versions of IE). There is no single <table> on the source.php output on mirrors carrying the new code, though there were many on the old layout [6 exactly on this page]. This does not only mean that this page is going to render quicker, but it also means that the new layout is 1515 bytes lighter (exact measure for this page). If you multiply this with number of requests coming in for different two column pages, you realize that this will be good for our servers, if the layout prooves to be working in other browsers too, and we expand its usage. I am conserned about two possible problems we would have with this layout, the box model bug in IE5 and the 3px rendering bug in IE. I have not yet added any code to prevent these from appearing, as the layout was perfect for me in Mozilla and Konqueror, and I was not keen on blind guessing. Please see the source page, and check it out in the browser you use. I would very much appreciate proposed solutions in case you have a clue on how to fix something which you experience to be broken.
